Born into the theater

I was born into the theater.
Literally. My mother, the famous actress, scored a year-long run in Oklahoma! via that infamous casting couch.
Nine months in, she still refused to give up the spotlight to her understudy.
The costume girl eventually went insane.
During the matinee, her water broke in Act 2, but she didn’t miss a line.
She concealed contractions with howls of laughter and screams of joy.
The curtain fell, I was born, and she was holding me to her breast through four curtain calls.
If you think that’s bad, that bastard director added it to the script!
